A novel and efficient route for the synthesis of 5-nitrobenzo[d]oxazole derivatives
چکیده انگلیسی
In this paper, we report a novel and efficient route for the synthesis of 5-nitrobenzoxazole derivatives starting from 2-fluoro-5-nitroaniline and various benzoyl chloride derivatives under solvent-free conditions at 130 (C in the presence potassium carbonate. Benzoyl chlorides easily underwent nucleophilic acyl substitution followed by intramolecular cyclization via concomitant removal of fluorine to obtain the title compounds in high yields.
